Abstract
An envelope and blank structure is disclosed for use with promotional mailings. The envelope includes at least one window opening in its front panel which is normally covered by a sheet of transparent window material. The outer surface of the window material is in turn applied with a non-transparent coating for obscuring a message included within the envelope beneath the window opening. The message may subsequently be revealed without opening the envelope by scratching or rubbing the coating from the window material.
